Subcategory archive does work with any name as parent category in URL
|Reported by:||ocean90||Owned by:|
Parent category is parentcategory and his sub category is subcategory.
The URL will be domain.com/category/parentcategory/subcategory.
The problem is, that you will get the same page if you use any words as parentcategory.
IMO redirect_canonical should do his work here (and sometimes it does).
